The Astronode S from Astrocast is a Satellite Communication Module for highly integrated, battery-powered IoT systems. This low-power module enables bi-directional satellite communication on a single battery for a period of up to 10 years. The Astrocast nanosatellite LEO network is designed to enable low latency global transmission of messages with additional unicast and multicast downlink capability. This module has an end-to-end network latency of 15 min (location dependent). It has a low-cost patch antenna for fully integrated designs with a recommended ground plane size of 65 x 65mm.
The Astronode S requires a DC supply of 3.3 V, has a peak power consumption of 0.35 W (in Tx mode), and consumes less than 500 nA of current in deep sleep mode. It has a UART serial interface and 2-level 256-bit AES encryption with unique device keys. This module is available in a surface-mount package that measures 35 x 31 mm for trouble-free integration and soldering onto a PCB. It is ideal for use in maritime (container tracking, fishing buoys), agriculture (fuel management, precision farming), and environment (weather data, flow monitoring) applications.
